By remediating a cluster against an image, you apply the software specified in the image to all the hosts in the cluster. So, by remediating a cluster, you make the non-compliant hosts compliant with the image that you set for the cluster.

During remediation, the hosts in the cluster are remediated in sequence. The hosts that have the incompatible compliance state are not remediated.

If a vCenter HA failover is initiated during the remediation of a cluster, the remediation task is canceled. After the failover finishes, you must restart the remediation task on the new node.


Verify that you have the proper privileges. See vSphere Lifecycle Manager Privileges For Using Images.
